Thermal solid phase diffusion

What is special about this process?

What is special about this process?

The special feature of this process is the particularly good bond with the base material that results from the diffusion of the zinc into the base material.

FuseCoat®

FuseCoat® is a set or processes which consist of zinc thermal diffusion + passivation + functional or decorative coating. Corrosion and wear protection coatings, decorative coatings, non-stick coatings, slide coatings as well as traction coatings are used.

FuseCoat® is pursuant to DIN EN ISO 17668 or DIN EN 13811 and DIN EN 15773:2010.

  • Characteristics

    FuseCoat® has the following properties:

    • High hardness
    • Active cathodic corrosion protection
    • High impact resistance
    • No hydrogen embrittlement
    • High temperature resistance
    • Anchoring by atomic bonding with the basic structure / base material
  • Base Materials

    The following base substrates are suitable for zinc thermal diffusion by FuseCoat®:

    • unalloyed carbon steel
    • low alloy steel
    • heat-treated steel
    • high-performance steel
    • cast iron and grey cast iron
    • sintered metal
  • Field of Application

    FuseCoat® is used wherever there is a need for outstanding cathodic corrosion protection and other functional and decorative properties combined in a duplex coating, e.g. in the automotive and construction industries, traffic engineering, wind power, the oil and gas industry or offshore.

Zinc-Diffusion-Coat®

Zinc-Diffusion-Coat® is a set or processes which consist of zinc thermal diffusion + passivation.

Zinc-Diffusion-Coat® is pursuant to DIN EN ISO 17668 and DIN EN 13811.

  • Characteristics

    Zinc-Diffusion-Coat® has the following properties:

    • High hardness
    • Active cathodic corrosion protection
    • High impact resistance
    • No hydrogen embrittlement
    • High temperature resistance
    • Anchoring by atomic bonding with the basic structure / base material
    • Good primer surface for additional coatings
  • Base Materials

    The following base substrates are suitable for zinc thermal diffusion by Zinc-Diffusion-Coat®:

    • unalloyed carbon steel
    • low alloy steel
    • heat-treated steel
    • high-performance steel
    • cast iron and grey cast iron
    • sintered metal
  • Field of Application

    Zinc-Diffusion-Coat® is useful wherever extreme, active cathodic corrosion protection is required, e.g. in the construction and automotive industries, in traffic engineering, wind power or offshore technology.

ZTD Coat®

ZTD Coat® is a special corrosion protection coating which thermally modifies the surface of a wide variety of components using the patented zinc thermal diffusion method. The resulting protective layer forms a strong bond with the carrier material.

  • Characteristics

    ZTD Coat® has the following properties:

    • Long-term corrosion protection
    • Uniform layer thickness, even with complicated geometries
    • No hydrogen embrittlement
    • Protection from damage, even during moulding processes
    • Protection from seizing
    • Oxidation resistance
  • Base Materials

    The following base substrates are suitable for zinc thermal diffusion by ZTD Coat®:

    • unalloyed carbon steel
    • low alloy steel
    • heat-treated steel
    • high-performance steel
    • cast iron and grey cast iron
    • sintered metal
  • Field of Application

    ZTD Coat® is used primarily in the automotive industry and anywhere where excellent corrosion protection must be combined with other functional and decorative properties. Aalberts surface treatment fulfills all specifications of international car manufacturers.
